For homeowners in NW3, where housing ranges from georgian houses to edwardian houses, this approach often makes particular sense because it works within the existing building envelope.

In Frognal, the specific structural characteristics of the local housing stock — georgian houses and victorian houses — create both opportunities and constraints that an experienced architect can navigate effectively.
